I don't lie on my LinkedIn profile. I keep it pretty realistic with where I've worked and what I've done. I'll be looking for new work sometime next summer. In my interviews, I bring evidence of the work I've produced in case the conversation comes up. People tend not to believe you otherwise.
More importantly, though, I keep my actions public. What I mean is that I don't put in extra hours, or work for free, at no cost. I make sure that if I'm involved in a project, I take charge where needed and stand back when necessary.
I never liked embellishment. Write what you actually did and make sure you can back it up.
